D-Link DES-1210-28P Web Smart 24-Port Fast PoE Ethernet Switch

Extensive Layer 2 Features

Equipped with a complete lineup of L2 features, this switch includes IGMP Snooping, Port Mirroring, Spanning Tree and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfer. At 2000Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss.

Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. Cable Diagnostics are designed for network administrators to quickly examine the quality of the copper cables and determine the type of cable error.

QoS Bandwidth Control

The switch is perfect for deployment in a VoIP environment, as it supports Auto Voice VLAN and Differentiated Services Code Point (DSCP) QoS for VoIP application. Auto Voice VLAN will automatically place voice traffic from an IP phone to an assigned VLAN and by doing so enhance the VoIP service.

With a higher priority and individual VLAN, this feature guarantees the quality and security of VoIP traffic. DSCP marks parts of an IP packet, enabling different levels of service to be assigned for network traffic. With Bandwidth Control, the network administrator can reserve bandwidth for important functions that require a larger bandwidth or might have high priority.

Secure Your Network

The innovative D-Link Safeguard Engine function protects the switch against traffic flooding caused by virus attacks. The DES-1210-28 switch supports 802.1X port-based authentication, allowing the network to be authenticated through external RADIUS servers.

The Access Control List (ACL) feature enhances network security and helps to protect the internal IT network by allowing an administrator to restrict the access of a network through a variety of means including MAC address, IP, UDP/TCP, and even VLAN ID.

The switch supports ARP Spoofing Prevention, which prevents the network from being cut off or eavesdropped by hackers using faked ARPs.

For added security, DHCP Server Screening screens rogue DHCP server packets from user ports to prevent unauthorized IP assignment.

Versatile Management

The SmartConsole Utility easily allows customers to discover multiple D-Link Web Smart Switches within the same L2 network segment. With this utility, users do not need to change the IP address of their PC and it provides an easy initial setting of the Smart Switches. Switches with the same L2 network segment that are connected to the user's local PC are displayed on screen for instant access. This allows extensive switch configuration settings and basic configuration of discovered devices such as password changes and firmware upgrades.

D-View 6.0 is a Network Management System that allows for the central management of critical network characteristics such as availability, reliability, resilience, and security in a consistent way. D-View 6.0 provides a useful set of tools for network administrators who want to effectively manage device configurations, fault tolerance, performance, and security.

Command Line Interface (CLI) management through Telnet makes the adjustment of basic settings such as password changes or firmware and configuration file uploads possible.

Seamless Integration

The Web Smart switch DES-1210-28 is designed to provide small-to-medium sized business users complete control over the network. With Ethernet and Gigabit copper ports capable of connecting to existing Cat.5 twisted-pair cables, this switch eliminates the need for a complex reconfiguration process. The DES-1210-28 allows for a flexible connection to a backbone or servers.

All ports support auto-negotiation of MDI/MDI-X crossover, or configurable auto MDI, and therefore do away with crossover cables or uplink ports.
